T 0 all whom it may concern.'

Be it known that I, THOMAS H. MATHIAS, a citizen of the United States,residing at Buffalo, in the county of `Erie and State of New York, haveinvented new and useful Improvements in Machines for Removing DefectiveSurfaces of Metal Bars, of .which the following is a specification.

My present invention relates to the removing of defective surfaces fromiron or steel bars, or blooms, which have first been worked down more orless from the ingot as de; scribed in my Patent No. 1,120,831 for a process and consists in a machine whereby that process may beconveniently practised. The ingots from the soaking pit show asuperficial skin lower in carbon than the body of the metal. As theingot is worked down and elongated into a bar, by more or less rolling,this skin becomes thinner, but is always present in the finished rail orother product and is a source of weakness. Furthermore as the ingotisrolled out into the bar longitudinal seams develop in this skinextending substantially parallel and are an- To remove this defectivesurface as the source of these weaknesses I invented my process, and topractise said process l have designed the machine here described.

Certain difficulties attend the removal of such surface due principallyto the high temcutting-tools having peripheral teeth, means for rotatingsaid tools at a high speed andV means for feeding the 4bars operatedupon to the tools and guiding them therefom. It is also important thatthe particles ofthe surface, or spittings be guided away fromv the barand removed from the machine rapidly without danger of welding together,or.

of sticking lto the parts of the machine, or of again coming-in contactwith the bar from which they have been removed. To that 'end I havedevised means for cooling and 'eX- pelling said spittings withoutaffecting the temperature of the bar, or interfering with the functionsof the machine, or with the operation of rolling. It is also desirableto provide means foradjusting the cutters and for cooling the variousparts ofthe mechanism. v

Fig. 5 is a front elevation thereof and Fig.

v6 is a vertical sectional view looking in the opposite direction toFig. 4. Fig. 7 is a Aview similar to Fig. 1 illustrating a modified formof machine for operating on more than one surface of the bar. Fig. 8 isa front' elevational view of the cutter housing showing theV arrangementof guiding parts, as though taken on section line 8 of Fig. 1 lookingtoward the cutter; Fig. 9 is a side elevation illustrating the housingsfor the cutting tools of the machine of Fig. 7 with the cutters andother parts omitted; Fig. 10 is a detail view showing the manner ofadjusting the guides. l

1n the embodiment of my invention illustrated in Figs. 1 to 6 l haveshown an approved type and arrangement of cutting tool for removing thesuperficial skin from one side only of the bar. As there shown, the bar`1 is passed forwardly between the feed rolls 2 2 and 3 3 of the machineand beneath a rotary cutter 4 arranged intermediate of the rolls andabove the bar. rlhe bar 1 referred to may be understood as any bar beingrolled as for instance a rail which has progressed in the rollingoperation about one quarter toward completion. rlhe cutter 4f desirablyis rotated at high speed and is provided on its periphery withcuttingteeth of suitable formas indicated in Fig. 6, to act upon the bar as itis passed beneath the cutter. I

A supporting roller 6- is jounaled beneath the cutter 4; accurately andrigidly to supportv the bar as it is being cut and this'roller 6 isarranged to be driven in unison with the rollers 2-2 and 3--3 throughconnections to lbe described. As all of the rolls are of a size theywill act uniformly in advancing the bar.

The feed rolls 2-2 and 3--3 are liournaled in suitable oppositelyarranged `bearings ',8--8 adjustably supported on standards or PatentedNew. es, ieee.` y

housings 9-9. The bearings are fitted to suitable ways in the housingsand the upper bearings' are supported in the customary manner upon thelower bearings with suitable spacing liners between them. Similarly, thelower feed rolls are arranged to be adjustable by the positioning ofliners or distance bars 14 interposed between the housings and the lowerbearings. The bearings so spaced and supported are rigidly clamped inposition by means of the screw-down boltsl 10-10 provided with handlevers 12-12 and threaded to the housing caps 11-11. Similarly thesupporting roller 6 is journaled in bearings fitted within the" cutteror tool housing or standard 16 and adjustable by means of liners 18.

The cutting tool is carried by a tool shaft 20 adjustably journaled and`driven in an improved manner hereinafter described and desirably it isrotated in a reverse direction to the movement of the bar upon which itoperates. The removed particles of heated metal or spittings aretherefore thrown forwardly of the cutter and an important feature of thepresent invention consists in the means employed for removing thesespittings from the machine without danger of clogging by the weldingtendency of thel heated particles and consequent interruption of theproperoperation of the machine. The means which l have devised for theeiiicient and successful removal of theheated particles consists in anarrangement of deflection box or chute havlng associated therewith waterjets in a manner whereby the particles are intercepted and cooled by thewater so that they doI not stick together, and under the impulse of thejets they are ejected from the machine. As the interior of the box islikewise continuously sprayed by the jets there is no possibility of theparticles adhering thereto to cause a stoppage from that source. The boxis here shown at 25 inFigs. 1 and 2 and is shown in detail in Figs. 3 to6'.

As best shown inFigs. 3 land 6 the deflection box 25 is open at itsfront and into this opening 26 the cutter 4 extends whereby theparticles removed thereby are thrown directly into the box. The sidewalls 27--27 and the top wall 28 of the deflection box are arranged tobe in close proximity to` the cutter so as to completely receive andretain the particles and at the, bottom of the box there is arranged ahinged baile plate 'dition whereby there is no danger of clogging of thepassage.

As will be readily understood the action of the water thus cools andlubricates the particles and also 'ejects them from the .machine withoutpermitting them to freeze to the chute which would interrupt theoperation or to cling to each other in which condition they would bediiicult to handle.

The nozzles as shown are suitably flared or flattened and the rear wallof the box is suitably curvedV to deflect the particles outwardlythrough the chute. The delecting box is suitably supported in position,as shown being bolted to the cutter housing 16. From the-dischargeopening of the chute the particles drop into a hopper. whence they maybe removed mechanically by anyv suitable means. Y

Suitably supported on the housing 9, in advance of the rolls 2-2, anentry guide 40 is arranged to guide the bars as they enter between therolls. The'guide 40 is formed with curved sidel guide flanges 41-41 andis provided with hardened metal bearing inserts 42-42 as shown. A topentry guide 43 is pivotally supported at 43 and adjustable by means of aturn buckle support 44 as shown.

Desirable guides are also employed to guide the advancing bar withrelation to the cutter and tothe rear feed rolls 3*-3. I

have devised guides therefor comprising suitable guide arms held inposition to engage the bar on all four sides whereby it is supported foradjustment with. relation to the cutter. To that end theupperl` guide ispivoted upon a pin 46 and the side guides are pivoted upon pins 47-47;the pins 46 and 4 7 being carried by a supporting frame 48. This frame48 is itself pivotally supported on a pin 50 carried by suitablebrackets of the housing 9. The lower guide 45 is rigidly secured to theframe 48 and is arranged to be engaged from beneath by an adjustablerest shoulder or threaded into a projection of the cutter housing 16.Thus by adjusting of the screw 52 the lower guide 45 and with it tnesupporting frame 48 are rocked to adjust the vertical relation of theguide arms to the cutter.

For laterally adjusting .the side guides 45 I have arranged vforsupporting these guides screw 52 bar thereto.

tures in the frame 56 and having nuts 60.

threaded on their outer ends and confined between these nuts and theframe coiled compression springs 61 are fitted to the studs to exert anoutwardly directed force on the studs and arms. In consequence theguides are normally held in an outward position. Opposed to the actionof the springs 61 I have provided adjusting or set screws 64 threaded tothe frame 56`to engage the guides and by theiradjustment accurately tomaintain the guides in position. The set screws 64 have squared headsfor the use of a wrench thereon and locking nuts 65 are threaded thereonfor securing them when adjusted.

The upper guide is supported at its free end to be independentlyadjustable relative to the lower guide 45 by means of a threaded rod 66attached thereto at its lower end and received at its upper end in a lug67 of the frame 16 to be adjustably secured bythe nuts 68-68 threaded onthe rod.

The front guides referred to are extended toward the cutter to be insubstantially as close proximity thereto as is permissible so as to-insure greater accuracy in guiding the Similarly constructed butreversely arranged guiding parts are provided to the rear of the cutterof which rear guides 145 are forwardly extended from a frame 148 to bein guiding engagement with the bar at their forward ends immediatelybehind the cutter. The frame 148 is similar to frame 48 and is similarlysupported upon a pin 150. Likewise the lower guide arm 145 is carried onthe bracket 148 and has thereon the frame 156 corresponding to frame 56.The upper guide 145 is pivoted on pin 146 carried in the bracket 148 andthe side guides 145 are adjusted in the frame 156 in similaf" manner tothe adjustment of the side guides 45 in frame 56 described but these,rearward side-guides, as shown, are extended rearwardly between therolls 3 and pivoted upon vertical pins 147 carried by a supportingbracket 150. The side guides 145 being long and pivotally supported atthe front may be adjusted in and out without `substantially changingtheir angle to the work.

6 are driven in unison and the cutter preferably is driven independentlythereof. The rolls are driven from a suitable source as the motor 75indicated, through connections here shown comprising a drive-gear 76 onthe motor shaft in mesh with a gear 78 on suitably journaledcounter-shaft 79. Upon shaft 7 9 is a small gear 80 in engagement with alarger gear 81 on shaft 82 and the power is transmitted directly fromthis latter shaft to the rolls 2. For that purpose the shaft 82 isarranged to be in parallel alinement with the upper of the rolls 2 andis coupled thereto by a suitable coupling 84. The shaft 82 isjournaledat one end in a standard 85 and beneath it within the samestandard, is journaled a shaft 86 parallel to the lower ofthe rolls 2and coupled thereto by a suitable coupling and the two shafts 82 and 86,are rotatably connected by gears 88-89 on the respective shafts by meansof which the lower roll is driven. A similar manner of driving the rearpinch rolls 3-3 is employed wherein upper and lower shafts 90-91 arejournaled in va standard 92 and rotatively connected by gears 93 and arearranged in parallel relation to the upper and lower pinch rollsrespectively and connected directly thereto by suitable couplings 05. Aconnecting shaft 96 is suitably j ournaled at right angles to the shafts82 and 90 and has afxed thereon ruiter gears l(1T-98 in engagement withsimilar gears 99-100 respectively on the shafts 82 and 90 whereby thelattershaft is driven from and in unison -with the shaft 82 and theforward and rear ward feed rolls are given a like rotation. Acorresponding movement isimparted to the supporting roller 6 throughtheengagement of the miter gear 102 with coacting gear 103 on a roll driveshaft 104 journaled in parallel relation to and coupled with the roller.A desirable' arrangement of the rotary cutter is, as shown best in Fig.5, with the circular cutting tool 4 clamped by annular flange 106 to asuitable cutter disk 107 keyed onto cutter shaft 20. The shaft 20 isjournaled in bearing blocks 108 fitted to vertical ways in the oppositestandards 109 of housing 16 and at its other end is similarly journaledin bearings tted to ways in opposite standards 112-112. Between thestandards 112-112 the cutter shaft 20 carries a fixed pulley 115 drivenfrom a drive pulley 118 on the axle of a driving motor 120. The drivingpower is thus communicated from the motor to the cutter whereby thelatter is driven preferably at a high speed. l

The bearing arrangement of the cutter shaft provides for simultaneousadjustment of all of the bearings 108 and the similar bearings in thestandards 1'12-112 (not shown) vertically within the standards so as toshift the cutter therewith when deported upon suspended .supportingvrods- 122-122 as best shown in Fig. 9. relhese lrods 122 are passedupwardly through the cap 16 ofthe housing 16 and have threaded on theirupper ends the nuts 124-124 beneath which are arranged the coiledcompression springs 125 fitted to the rods. The springs 125 are thusconfined between the nuts 124 and the cap 16 to rest upon the ylatterfor supporting the cutter bearings 108 which rest upon supporting keys126 carried by the rods. Adjusting of the bearings is directly effectedby means of threaded adjusting rods or stops 127 threaded to the caps 16to bear upon the upper surface of the bearings and thereby determine theposition of cutter. All of the bearingsl for the cutter shaft aresupported in the same manner and are arranged to be simultaneouslyadjusted by connections now to be described.

Fitted to the upper end of each of the adjusting rods 127 is a bearingbracket 128 providing horizontal bearings for an elongated adjustingshaft 13() horizontally supported in the bearingsso provided. Thisadjusting shaft 130 has affixed thereon small bevel gears 131 inengagement with gears 126 aixed to each of the adjust-ing rods 127whereby upon turning of the shaft a like rotative movement will beimparted to each of the adjusting rods -to adjust its related bearingsand upon one end of the shaft 13() is provided a hand wheel 132 to`conveniently effect 'this adjustment,

At points"134 and 135 (Fig. 1) water jets are directed against theactive surface of the cutter to prevent adhering of the heated metalthereto and the water, which is introduced in sufficient volume for thatpurpose, also has a desirable cooling action on the cutterwhichcontributes to the successful operation of the machine. A suitable.pro-

tective hood 136 is supported above the cutter as shown. The lowermostjet 135 also performs an important function of cooling the particles andwetting them and also the baille plates so that the particles do notadhere to the latter'. i

While the machine described employs but a single cutter for removing thesuperficial skin from one surface of the bar only it will be readilyunderstood that a plurality of such cutters may be employed simul,

taneously to operate upon two or more surfaces of the bar if desired.`In Fig. 7 I have shown such a machine wherein the supporting roller 6'ofthe machine irst described is replaced by a second cutter 4 arranged tooperate upon the under surface of the bar as shown. This lower cuttermay be driven in any desirable manner not necessary to be shown.

This lower cutter may be driven from any source of power not necessaryto be shown. 1t is here shown carried by a cutter shaft 20 arranged tobe adjustable by being supported in similar manner to the support of theupper cutting tool 4. Referring to Fig.

, 9, 108. indicates one of the bearings for the cutter shaft 20', thesebearings operating in the guide-ways of the standards. The adjustingconnections provide for adjusting the bearings 108 from beneath and comyrlhe springs 125 are confined between nuts 124 threaded onto the rods122 and washers 126 received on the lower ends of the upper rods 122.The bearing arrangement for the lower cutting tool isthus generallysimilar to that for the upper tool whereby it may be adjusted withreference to the bar upon which it acts.

A deiection box 25 is associated with this lower cutting tool forejecting of the particles removed from the bar and may be in the form ofa curved hood, as shown in Fig. 7, to deect and discharge the spittingsdownwardly beneath the cutter. At 35 is indicated the nozzles fordirecting the jets of -water `into the deection box to intercept andcool the particles and lubricate the sides of the box in the mannerdescribed. At 30 l have indicated a suitable resilient the bar and guidethe particles into the boxl 25. The position 'of the nozzles 35 is suchthat the jets therefrom will impinge both on the baille 30 and on theteeth of vthe cutter 4f whereby they are lubricated to the end ofpreventing the particles adhering thereto.

While the process of my said Patent No. '1,120,831 was intended to bepractised in any manner that might be desired without reference to anyparticular machine, yet the machine Ahere described is particularlyadapted to the practice of said process. By means of this machine thesurfacelmay desirably be. cut from blooms and bars of various sorts.This machine has proved successful in practical use for a considerablepe.- riod and is particularly adapted-for use in connection with theproduction of different A the scope of the appended claims withoutdeparting from the spirit of my invention.
